I have not heard this before but it's a very good bit of information. I will email Urocare and see if they changed their formula... I'm testing some new silicone based glue, will post if its any better/worse/etc...
Pretty sure I had some bad luck with the last glue I ordered. That was when I was having all sorts of problems with it not holding for an entire day.
I accidentally didn't close it all the way the last time I used it and it hardened. I ordered some more and have been pleasantly surprised that it's VERY sticky. I did a full day of diving (put it on at 5am and took it off around 4pm) and had no leaks from the she-p. Unfortunately, I dumped water down my neck seal twice and it made it all the way down to the crotch area and then I got worried that I was leaking....nope, yay for sticky glue!
Anyone else ever get unlucky and have glue that's not quite as sticky?
